Unfortunately, HD Tune does not generate any fancy independent graph outputs in particular, so I just used a screenshot. Like our HD Tach results on the previous page, the line was a bit bumpy, but remained fairly flat on average. It differs slightly in magnitude than the other program -- probably due to testing algorithms used -- but its performance characteristics are identical in practice. Other than that, the results were commendable across the range; the recorded access time was very low, as we would expect from a solid state drive. The Gigabyte M.2 PCIe SSD 256GB posted an average of 525.7MB/s for its sequential read speed. Do keep in mind the discussion we had on the previous page, as it still applies here.
